RIM CONSTRUCTION.

Specification of Letters Patent.

Patented July 22, 1913.

Application filed March 25, 1912. Serial No. 686,004.

:1 b all whom it may concern:

Be it'known that I, J onx CLARENCE COLE, a citizen of the United Statesof America, residing at Chicopee Falls, in the county of Hampden andState of Massachusetts, have invented new and useful Improvements in RimConstruction, of which the following is a specification.

This invention relates to that class of apparatus designed to facilitatethe handling of tires as the latter are placed on or taken off the wheelof a vehicle.

Specifically it relates'to a dual tire-holding construction, viz.,one inwhich the telly of the wheel carries two fixed rims, each one of whichreceives a removable rim and tire.

The construction is particularly adapted for use with trucks, althoughnot confined thereto.

The object of the invention is to provide means whereby the removablerim with its tire which is .next to the body of the vehicle can beremoved easily and conveniently.

Other objects of the in ention will be brought out in the detaileddescription and annexed claims.

In the drawings forming part of this application,-Figure 1 is an axialcross sectional view of the invention. Fig. 2 is a cross sectional viewon the line 2-2, Fig. 1. Fig. 3 is a plan View of a detail ofconstruction taken on the line 3- -3 of Fig. 1.

Referring to the drawings, the telly h has a plate m fastened thereonwhich, in turn, has two rims d and e fixed thereto. The plate m could bedispensed with, but is used for convenience. The fixed rim 6 is slightlylarger in diameter than the fixed rim d which step-up arrangementpermits the removable rim '1' (larger in diameter than'either the rims dor e and. carrying the tire b) to pass over the fixed rim (Z and ontothe fixed rim 6. Any suitable fas tening device, such as 70, comprisingflanged bolts and beveled expanding rings, is used to bind the removablerim to the fixed rim, as shown. After the removable rim is fixed on therim e, a blocking ring 0 is slipped on the fixed rim (Z which has aflange to receive and position the same. The i diameter of the fixed rimd with the blocking ring 0 added thereto, is equal to that of the rime.' The removable rim 7 carrying the tire a which has the same diameteras the other removable rim, is placed on the blocking ring 0 which has aflange to position it and a holding device t, similar to the device is,to hold it to said blocking ring. Each removable rim has one or morepositioning blocks g fast thereto which fit in corresponding recesses inthe rim 0 or in the blocking ring 0. Before the blocking ring is p lt inplace, the block or blocks 7 of the inner rim w pass throughcorresponding slots f in the rim (Z. In addition to positioning theremovable rims on the fixed rims by the blocks 5 and recesses, asstated, said blocks fitting in the recesses prevent any relativecircular movement of the removable rim with respect to the fixed rim,which is important in devices of this character.

hen the parts have been all assembled, as indicated above, and it isdesired to remove both tires from the wheel, they can be removed fromthe most convenient side, that is the side away from the body of thevehicle, without removing the wheel from its axle. This is done asfollows: Referring to Fig. 1, the holding device 25 is lowered to theposition shown, the tire a with its rim is slipped off the blocking ring0, the latter is removed from the fixed rim d, and inasmuch as thelatter is of smaller diameter than either rim r, the tire I) can beslipped thereover with its rim 1' which gives the desired result. Inthis last operation the blocks 9 pass through slots f provided for thatpurpose in the rim d.

Applicanthas described his invention specifically as applied in thedetails shown. The invention, can, however, be applied in other specificforms.

What I claim, is

1. In combination, a felly, two fixed rims attached thereto, one smallerin diameter than the other, a blocking ring of the same diameter as thelarger. rim. arranged to fit over the rim of the smaller diameter, tworemovable rims of the same diameter, one arranged to fit on the fixedrim of the larger diameter and the other arranged to fit on the blockingring-holding devices to bind the removable rim to the larger fixed rim.together with other holding devices to bind the smaller fixed rim,blocking ring and; the other removable rim together, all ior the purposedescribed.

2. In combination, a fully, two fixed rims attached thereto, one oflarger diameter than the other, a blocking ring of the same diameter asthe larger rim arranged to fit on the smaller rim which has a flange toposition it, two removable rims of equal diameter either one of which isinsertible over'the smaller rim when the blocking ring is not mountedthereon to take its place on the larger rim, and the remaining removablerim being adapted to fit on the blocking ring, fastening means to bindsaid smaller rim, blocking ring, and one removable rim together, andother fastening means to bind the other removable rim and larger rimtogether, all for the purpose described.

3. In combination, a felly, two fixed rims attached thereto, one oflarger diameter than the other, two removable rims of equal diametereither one of which is adapted to pass over the smaller fixed rim andfit on the larger fixed rimfor attachment thereto, and means to makesuch attachment, removable means adapted to fit on said smaller fixedrim to build a bearing surface on it to a diameter equal to the largerfixed rim, whereby after one removable rim has passed over the smallerrim for attachment to the larger rim, said removable means may be fittedin place and the remaining removthan the other (the fixed rim of smallerdiameter having on its circumference axial slots) two removable rims ofequal diameter either one of which is adapted to pass over the smallerfixed rim and fiton the larger rim for attachment thereto, and

means to make such attachment, devices on each removable rim to fit intorecesses in the fixed rim for preventing relative circular motiontherebetween, removable means 1 adapted to fit on said smaller fixed rimto 4 build a bearing surface on it to a diameter equal to the largerfixed rim, whereby after one removable rim has passed over the smallerrim for attachment to the larger rim, said removable means can be fittedin place and the remaining removable rim can be placed thereon forattachment thereto, and means to make such, attachment.
